libnvme(2)

💖 NAME 💖

okay so bestie, this is the manual page for libnvme, section 2 (the API Manual, for all my systems-programming girlies) ✨ and today's main character is:

struct nvme_vs_perf_attr — the Vendor specific performance attribute structure 🫶

that's it, that's the name, and yes it is giving "very specific little C struct" energy and we are obsessed 💅

---

✨ SYNOPSIS ✨

here's the whole glow-up, laid out exactly as-is, no cap:

struct nvme_vs_perf_attr {
    __u8 paid[16];
    __u8 rsvd16[14];
    __le16 attrl;
    __u8 vs[4064];
 };

look at her. four members. perfectly balanced. the way the byte math just works 😭👑

---

🎀 Members 🎀

let's go member by member, iykyk, nothing skipped, everything included 🌸

• paid — the Performance attribute identifier 💖 (sixteen whole __u8s of it, she's a big one)
• rsvd16 — Reserved 🙈 (do not touch, that's not your business, the name literally says reserved)
• attrl — the Attribute Length ⭐ (a lil __le16, cute, little-endian, main character energy)
• vs — Vendor specific 👑 (four thousand and sixty-four __u8s of pure "ask your vendor" energy, that's 4064 fr fr)

---

⚠️ real talk: rsvd16 is Reserved. leave her alone. and vs is Vendor specific, so whatever's in there is between you and your vendor, bestie, i cannot help you 💀

---

so yeah, that's the whole struct, every field accounted for, no detail left behind, slay 🦋

and that's the vibe check for this one, signed off from the struct nvme_vs_perf_attr page of the libnvme(2) API Manual, dated July 2026 🎀 periodt 💜🌈
